I was doing a test run on my new BK today and all was great until I ran auto-tune. I ran it up to 150 deg. and set auto-tune to go at 160. as it was doing it's thing I was back and forth doing some other chores. All seemed great, unit was flashing AT just as the HLT one had done when I ran it. when it finally stopped flashing the temp reading was whacked, reading anywhere from 350-750. I thought that maybe the temp sensor type may have gotten changed, but it was still set at 21 (as it should for a RTD sensor). The set point still showed 160. I tried switching the HLT and BK sensor connections and still got the same thing (BK sensor worked fine with HLT PID). Has anyone seen this or have any clue what may be happening? Is there a way to re-set it to factory settings? a little frustrating as everything was fine until I ran the auto-tune
